' I I Application filed 111E119,"

To all whom it may come m.

Be it known that'l, ALnnnr N. VVooDnUrr, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Gopyrllolder, of which the following is a it is movable in one direction only by the intermittently operated means.

It is a further ob ect of the invention to provide a line spacer which 11s capable or movement to release the intermittently operat'ed mechanism in order that the same may be moved freely from the bottom or lower end to the upper'end'of the writing bed to re-position it with respect to the manuscript copy when the operator has finished each page. i Y I Referring to the drawings- Figure 1 is a side elevation or a copy holder constructed in accordance with the present invention;

Fig. 2 is a front elevation thereof;

Fig. 3 is a rear elevation partly in section of the invention;

Fig. 4 is a transverse sectional View taken on the line 44 of Fig. 3;

Fig. 5 is an end view of the upper end of the writing bed; i v 4 Fig. 6 is a detail sectional view of the carriage and a portion of its operating mechanism i .Fig. 7 is a detail sectional view showing the mechanism for preventing movement of the line spacer in one direction.

Referring moreparticularly to the drawings, the reference character 10 .designates the writing bed of the copy holder, and said bed is supportedat' one endby means of a suitable bracket 11, and at its opposite end by means of a bracket l2. The bracket 11 is rigidly secured to a flange 13, which in turn is rigidly carriedby the lower end Specifieationof Letter s ll atent.

to the underside or" the bed 10, as best shown to fold against the rear side ofthe bed 10 when the-"device is not in use. Each of these brackets 11 and "12 is-provided with a friction"producing covering in the form enema stay a mail of thewriting bed 10.; The bracket 12, how- I ever, is hlngedly secured in cars 14 securedj v in i 1g. 3, and said bracket 121s adapted 1 of a rubber 'sleeve'15 passed over that portion which engages the support by which the bracket 1s carried. j l

The writing bed 10-,is provided on its upper end with a flange 20, which depends therefrom, and extending beyond said flange and overlying the same is a channel 21in which is adaptedto engage a paper or-book clamping element 22. Thus the clamping element 22is mounted in a rigid bracket 23-carried by the rear face 01 the Writing bed 10, and the clamping portion thereof is adapted to be maintained in position in the channel 21 by means of a spring 24,0ne end of which engages'the'bracket as at 25, the

ll-igidlysecured at itsends to the flanges and 20 and arranged near one side. of

writing bed 10, 1s a rigid rod .30. The

the I reference character 31 designates a carriage, and said carriage has one of its ends turned about the rod 30 as indicated at 32, it being understood that the end ireely engages the rod 30 in order to permit of a sliding movement of the carriage 31. The oppo-. site end of the carriage 31 is provided with a substantially right-angular extension 33, and the body portion of the carriage 31 and the right-angular extension 33 are each provided with right-angular ears 34, each of which isperfo'rated as indicated by the reference character 35. rod 36 is recipro cativelymounted in openings in the'flanges 13 and 20. Rigidly secured to the-upper end of the rod 36, as at'37, is a spring 38, and said spring passes around a pintle or rigid pin39 and has its looped central poretion extendedfinwardly through a slot 40 in the flange 20 and engages a pin 41 to spring. r I The lower endyof the rod 36 1s screwthreaded as at 42'and engaged thereon 1s -a nut 43,; and 44' designates a button or thumb-engaging member by means of which .;prevent accidental displacement of the the rod 36 is reciprocated in the flanges 13 p and 20. .The nut 43 serves the means by which the throw of the rod 36 is regulated,

' to engage the reciprocating rod 36.

the like 60, on the under side of the earria e it being obvious that if the nut 43 is moved over the threaded portion 42 to a point nearer to the flange 13 than that shown in Fig. 3, the throw of the rod 36 will be 1na-' on the rear side of the bed 10.

Pivotally mounted on the carriage 81, as in perforated cars 50, 1s a line-spacing element 51, and said line-spacing element eX- tends around the side of the writing bed 10 to the front or top portion thereof, as indicated at 52. By means of a spring 53, one end of which is secured as at 54 to the carriage 81 and the other end embracing the line indicator as at 55, the portion 52 of the line indicator is maintained at all times in en agement with the paper or book car- 3 ried'b y the writing bed 10.

Suitably mounted by means of bolt or to 31, is a lever 61, and said lever 61 is provided with a notch or cut-out portion 62 adapted This lever 61 is provided with an angularly disposed thumb-engaging portion 63, by means of which it may be rocked about its pivot to a point where it disengages the rod 36 to permit of a free movement of the carriage upwardly of the bed 10. This pivoted leve 61 is maintained normally in engage with the rod 36 at one end 64: of a spi' mounted on a rigid bolt 66 secured to carriage. I

On the under side of the carriage is dog or similar pivoted member 68, pivoted as at 67, which dog is adapted to engage the writing bed 10 as-indicatcd by the reference character 69, the bed is corrugated or roughened in order that the dog or pawl 68 may obtain a grip thereon. Tllls dog or pawl 68 is normally maintained in engagement with the bed by the other end 71 of the spring 65, as best seen in Fig. 4. Y

The device operates in the following manner: I

Assuming that the device is positioned as in Fig. 1 and it is desired. to move the line indicator 52 to the left or downwardly of the bed 10,-th'e operator pushes upward the button 44 and reciprocates the rod 36 up wardlyof the bed 10. As this rod is reciprocated the pivoted lever 61 is rocked sufliciently to permit of a free movement of said rod, the dog or pawl 68 due to its engagement with the under side of the bed 10 preventing a movement of the carriage. When, however, pressure on the operating button is released under the influence of the spring 38, the rod will be returned to its normal po- As indicated at 70, a portion essee sition, and as it moves to its normal position the pivoted lever 61 bites upon the rod 86, and through this biting engagement .moves 7 the carriage with the rod on its return movement. v

From the foregoing it will be seen that the present invention provides a simple mechanism by which the line indicator of a copy holder may be moved step by step, the

distance of travel of which may be varied at the will of the operator.
